简介
This study is aimed to cost-effectively produce bacterial cellulose (BC) and impart it with antimicrobial activity by introducing bactericidal plant extracts into its three-dimensional matrix through an ex situ modification strategy. Briefly, the fruit wastes were utilized as the carbon source for BC production by Gluconacetobacter hansenii, followed by impregnation of bioactive extracts of Anogeissus dhofarica and Withania somnifera plants. FE-SEM and FTIR analyses showed the successful synthesis of BC-Anogeissus dhofarica (BC-A) and BC-Withania somnifera (BC-W) composites. Both BC-A and BC-W composites held 87% and 75% water of their dry weight, respectively, and each composite retained about 50% of originally absorbed water after 24 h. The bactericidal activities of BC-A and BC-W composites were investigated against Staphylococcus aureus and Escherichia coli as model Gram-positive and …
